This past Saturday marked the Saturday Night Live season finale, as well as Kristen Wiig's final SNL appearance as a regular cast member. It was kind of a big deal, and so this week's after party (there's an after party after each new episode) was, as they'd say in party-speak, off the hook. A few videos are beginning to surface on YouTube, and they're by no means of professional quality, but they do give a snapshot of what looks to have been a pretty wild night.

We're talking musical performances by Mick Jagger, Foo Fighters, Chevy Metal -- all of them playing together and playing with other SNL members, like the video featuring Kristen Wiig and the Foo Fighters belting out "I Love Rock N' Roll" with Andy Samberg and Jason Sudeikis, or Amy Poehler performing "Bad Reputation" with the Foo Fighters. The whole thing is just plain rad, and we wish we could've been a fly on the wall checking coats or something for this shindig.

Hopefully more videos of higher quality arrive soon, though we think this was just one of those "have to have been there" sorta deals where we'll just take what we can get. So here's what we can get right now.
